摘要： The invention concerns a rapid connection coupling (10) for transferring high-pressure gases and/or liquid, in particular for refilling a high-pressure, mobile container such as a gas cylinder with oxygen in a home environment or at a transfill station with a transfill device. The coupling in question comprises the following elements: a tubular housing (11), an outer sliding sleeve (18) which can slide relative to the housing (11); a number of radially expanding collet chuck elements (15) mounted on the housing (11) and provided with an engaging contour (17) which facilitates connection to a matching connection fitting (30); and a sealing piston (22) capable of sliding centrally inside the housing (11), the said sealing piston being brought into contact with the connecting fitting (30). Internal parts (e.g., pin 25b and pin 25c) of the coupling are characterized by having a reduced or minimized volume, thereby reducing the volume of fluid expelled when removing the fitting (30) from the coupling (10), thereby reducing the intensity of sound created by disconnecting the fitting (30) from the coupling (10). Additionally, the coupling (10) is characterized by being easy to use and by having a relatively low parts count.

摘要： A papermaking headbox with adjustable rigid slice lips especially adapted to permit deflection of the slice lips on a headbox utilized with a twin wire or crescent forming papermaking machine. The headbox comprises elongated slice lips extending into the forming zone located between converging papermaking wires or fabrics, the slice lips being substantially rigid in construction and affixed at their rearmost ends to headbox support members. One or both of the slice lips may be provided with a full width machined channel into which the actuating means in the form of relatively inflexible bellows are positioned. These metal bellows are in turn connected to a fluid supply means which cause a small axial movement only. The fluid supply means is adapted to supply a fluid under pressure of at least 1,000 pounds per square inch to the bellows, such that upon actuation of the bellows, the slice lip will be deformed, thereby restricting the slice opening. The full width channel provides a uniform flexure point for the adjustable slice lip.

摘要： A method and apparatus especially adapted to produce a ply separable web requiring substantially less energy input for drying. The apparatus comprises a headbox having at least three stock flow channels, at least one of which being adapted to convey conventional aqueous stock solutions and at least one other channel adapted to convey airborne fibers. The resulting web, having a significant portion of the fibers in a dry state, requires less energy to dry, and the distinct layers provide shear zones therebetween which permit ply separation upon creping. Different fiber types may be provided in different layers depending upon product attributes desired, and the products may be conventionally dried or may be throughdried. An alternative embodiment requires the mixing of airborne fibers with an aqueous solution adjacent to or within the headbox, producing only surface wetting of the fibers and reduced inter-fiber bonding.
